" PIN-CAM-ADJUSTiNG MECHANlISM.

Ap lication filed June a, 1924. Serial No. 717,496;

T 0 all .whom it mayconcem:

Be it known that I JOHN J. HALLiwELL,

acitizen of the United States, residing at Tuckahoe, county of Westchester, and State ofzNew York, have invented certain new and useful Improvements in P in-Cam-Adjusting hile'chanism, represented in the fully described and following: specification and the accompanying drawings, forming a part of the same.

In certain types-of anism, such, the web 15 for instance,

sheet abutment being a' cutting cylinder which acts to cut a sheetfrom the web. These rotary cylinders are which may the head of each sheet provided with sheet be in the form'of where pins are emand carry it partially around-the cylinder, and r as the pins take the length is cut from inder' by a tucking of folding off rolls.

inders, of course, varyvin speed being much slower sheet around, a sheet the-web.- The sheet tucked off the cylblade into the bite These folding cylthan the running speed.' This variation in the speed of the cylinder causes an irregularityin the foldsuccessive ing off of slow speed,

sheets.

the pins is not advanced past the cutting blade quite farenough, with the result that when the tucking blade acts to fold the sheet the tail of the sheet will lap over the 5 head end, thus producing an irregular fold. If the parts are timed to produce a regular fold at starting or at slow'speed, when the cylinder is driven at of the cylinder vancedtoo far past the result that the causes the the tucking blade, with head end of the, sheet high speed the throw sheet to be ad- .laps over on the tail end, thus producing an irregular fold.

It is one object of the present invention to produce a construction whereby the time tion to the folding rolls by a operable controller which may be operated ,while the machine is running, so that as T the speed. ofthefolder variesthe pins may be caused to take and release the sheet at line of the sheet and an even produced, and so that, the pins willnot tear handling 1nech-' as a rotary folder, forwarded .to. a rotary carrier,

usually a cylinder, and between it and a cooperating abutment; the form of 1 suchspeed, the starting For instance, -w ith acylinder at starting 'or. running at the end of the'sheet taken by at which the sheet taking devices take and release the sheet may be varied manually such time with respect to the folding blade that the fold will occur in the center fold folded product or otherwise, injure the sheet.

t'is afurther ob ect of the invention to produce a mechanism for effecting this which shall be of few parts, andwhich can be readily installed in machines already in use, as'well as in new machines.

in connection with the accompanying drawings, and the novel features pointed out in the claims hereunto annexed.

" Referring now to these drawings,-

Figure 1 is avertical sectional view of a rotary folder and associated parts illustrating'the invention; I V

Figure 2'is a side view, partly broken away, of one end of the construction shown in Eig. 1, looking in the direction of arrow 2 of that figure, andv l Figure 3 is a detail view vof the pin operatingcam, and one inea-nsfor shifting it. Referring now .to these drawings, the invention has been illustrated in connection with a rotary folder in which the carrier is in the form of'a cylinder. This cylinder is indicated by the numeral 1 and is supported on a shaft 2 suitably journaled in side frames 3 of any usuallor desired configuration. Cooperating with cylinder 1 is an abutment between which'and the cylinder the sheet is passed, this abutment in lustratedbeing a cutting cylinder 4; provided with cutting knives 5 which cooperate with the usual cutting woods 6 on the cylinder 1, this cylinder cutting sheets from a web The rotary cylinder 1 is provided with sheet taking devices, and these sheet taking devices are in the construction-illustrated in With these and other objects'not specifi the construction il-' operated.

the form of pins, two sets of these pins 7, 8 being provided. These pins act to take the head end of the sheet and forward it past a folding blade 9 which acts to tuck the sheetinto the bite of a pair of folding off rolls 10, 11;

According to the invention, means are provided for manually varying the time at which the pins take and release the sheet with relation to the action of the tucking blade, so that the sheet may be tucked off evenly and injury to the sheet due to a dragon the sheet by the pins is prevented. While the means employed for this may be varied somewhat, in the particular construction illustrated, there is provided an operating cam 12 provided with a groove 13. This cam is loosely mounted on the shaft 2 before referred to. The pins are mounted on arms 14 on shafts 15, these shafts having secured thereto arms 16 which carry rolls 17 which run in the groove 13 of the cam before referred to. It will be apparent that by shifting theposition of this cam the time of withdrawal of the pins may be varied with respect to the action of the folding blade, and means are provided by the present invention for manually effecting this shifting of the cam, these means being such that the shifting movement may be accomplished while the machine is running. As

shown, the cam is provided with means which will cooperate with the manually operable cam shifter for turning the cam on the shaft. In the particular construction illustrated for effecting this, a portion of the periphery of the cam is formed with worm teeth 19. In mesh with the teeth 19 is a worm 20 on an operating rod 21 supported in brackets 22, 23 mounted in the frame of the machine, this rod being provided with a hand wheel 24 by which the shaft may be can be shifted to vary the position of the pins as desired, and this can be done while the machine is running, the cam being adjusted so that the releasing movement of the pins is advanced if the press is running slow, or retarded if running fast, and this is done I through a very simple mechanism which may be easily embodied with a folding cylinder already in use as well as in new machines. In the best constructions means areprovided for steadying the cam, such as the pin and slot construction indicated by the numeral 25.

The parts may be driven in any suitable manner. As illustrated, the shaft 2, before referred to, is provided with a driving gear 26 driven from suitable source of power, not shown, and a second gear 27. This second gear is in meshwith and drives a gear 28 on the cutting cylinder 4, and is also in mesh with and drivesa gear 29 on the shaft 30 of the folding ofi r011 11, before referred pins, a cam for operating the With this construction the cam to. This gear 29 is in mesh with the gear 61 on the shaft 82 of the folding off roll thereby. driving the latter. 7

lVhile the invention has been shown and described in what is believed to be its best form, it will be understood that various constructions may be employed for manually shifting the cam, and the invention is not to be restricted to the details of construction described and illustrated.

What I claim is;

1. In a folder, the combination of a rotary carrier provided with sheet taking devices, a cam for operating the devices to take and release a sheet, and means manually operable while the machine is running for shifting the cam to adjust the time of operation of the sheet taking devices to take a sheet at the same point thereof but at different times. i 7
